Wilson fermions quark bilinears to three loops
F. Di Renzo, A. Mantovi, V. Miccio +2
Quark currents renormalization constants can in principle be safely computed in lattice perturbation theory. In practice, traditional lattice perturbative computations are quite cu…

Four-loop plaquette in 3d with a mass regulator
C. Torrero, F. Di Renzo, V. Miccio +2
The QCD free energy can be studied by dimensional reduction to a three-dimensional (3d) effective theory, whereby non-perturbative lattice simulations become less demanding. To con…

Fermionic observables in Numerical Stochastic Perturbation Theory
V. Miccio, F. Di Renzo, A. Mantovi +2
We present technical details of fermionic observables computations in NSPT. In particular we discuss the construction of composite operators starting from the inverse Dirac operato…
